东南丘陵区旱地耕作制度的类型、模式及关键技术

东南丘陵区旱地耕作制度主要包括多熟种植、轮作换茬和复地连作等三大类型，每一类型含有多种种植模式。为实现旱地耕作制度的高产、稳产和持续增产，东南丘陵区在发展旱地农业时主要采取了以下9项配套关键技术：（1）坡改梯田建设与综合治理技术；（2）集径流蓄水与节水灌溉技术；（3）培肥土壤与以肥调水技术；（4）深耕细作与保护性耕作技术；（5）抗耐旱作物与品种的选用及配套技术；（6）秸秆覆盖与地膜栽培技术；（7）丰产沟与丰产坑耕作技术；（8）旱地错季适应栽培技术；（9）化学制剂在旱作农业中的应用技术。

Types, Patterns and Key Technology of Dry Land FarmingSystems in Hilly Region of Southeastern China

There were three types of farming systems,including multiple cropping,rotation cropping and continuous cropping,in the dryland farming systems of the hilly region of southeastern China,and there were more than one patterns in every type of farming system.In order to realize the target of high yield,stable yield and sustainable yield-increasing for dryland farming systems,the following 9 key technologies were taken:(1) The construction of slope into terrace and the technology of its comprehensive management;(2) Setting water from runoff and irrigation technology with water-saving;(3) Fertilization of soil and fertilizer technology to divert water;(4) Deep tillage and intensive farming and technology of conservation farming;(5) Anti-drought crop and varieties and the selection and matching technology;(6) Cultivation techniques of covering with straw or plastic film;(7) Farming technologies of high-yielding ditch and high-yielding pits;(8) Cultivation techniques in the inverse season in dryland;(9) Technology of applying chemical agents in dry farming.
